Abstract
An amorphous alloy contains 54 at % or more and 79 at % or less Re, 8 at % or more and 28 at % or less Ir, and 11 at % or more and 18 at % or less Nb. A molding die includes a release film composed of the amorphous alloy. A method for producing an optical element, the method including press-molding a glass preform with the molding die.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. An amorphous alloy containing:
54 at % or more and 79 at % or less Re;
8 at % or more and 28 at % or less Ir; and
11 at % or more and 18 at % or less Nb.
2. A molding die comprising a film composed of an amorphous alloy,
wherein the amorphous alloy contains:
54 at % or more and 79 at % or less Re;
8 at % or more and 28 at % or less Ir; and
11 at % or more and 18 at % or less Nb.
3. A method for producing an optical element,
the method including press-molding a glass preform with a molding die comprising a film composed of an amorphous alloy,
wherein the amorphous alloy contains:
54 at % or more and 79 at % or less Re;
8 at % or more and 28 at % or less Ir; and
11 at % or more and 18 at % or less Nb.Cited by (0)
